Abstract (en)
The present invention provides a production method of a filament for which a hydrogel having lower strength than a native collagen gel can be used as a raw material. The present invention provides a filament obtained by the above production method and having excellent strength. The production method of the filament includes a step A of irradiating columnar hydrogel with ultraviolet rays; step B of vitrifying the columnar hydrogel after irradiation with the ultraviolet rays to obtain a filamentous hydrogel dried body; and a step C of rehydrating the filamentous hydrogel dried body to obtain a filamentous vitrigel, in this order. The filament is formed of a vitrigel dried body, and to which a hydrophobic solvent is adhered or impregnated.
